Abstract:
A pigment dispersion includes a pigment with at least one carboxylic acid group and a block copolymer including aromatic monomers having at least one carboxylic acid group or a salt thereof and aromatic monomers having at least one sulfonic acid group or a salt thereof. The pigment dispersions can be used for manufacturing inkjet inks and for the coating of colored layers.
